Abstract (en)

A method and a device for transmitting the downlink multiframe are provided herein. The method includes: setting positions of the Slow Associated Control Channel ,SACCH, frames and Traffic Channel, TCH, frames of multiple subscribers in a multiframe, wherein the SACCH frame of each subscriber and one or more TCH frames of other subscribers multiplex a same timeslot of the multiframe in a half-rate channel; and transmitting the multiframe in a preset timeslot. By adjusting the positions of the SACCH frames and TCH frames of the multiplexing subscribers, the SACCH frame of a subscriber and the TCH frames of other subscribers multiplex in a same timeslot for transmission; that is, the SACCH frames of each subscriber are staggered during transmission. This ensures normal transmission of the SACCH signaling of all subscribers and reduces the effect on the voice quality.
